Answer:

1. r+s²=49

2. pq²=24

3. -4xy-6x²+2x²y-6y= -54

Step-by-step explanation:

1. r+s²=0+7²=49

2. pq²=(6)(2)²=6(4)=24

3. -4xy-6x²+2x²y-6y= -4(3)(2)-6(3)²+2(3)²(2)-6(2)

                                = -24-6(9)+2(9)(2)-12

                                = -24-54+36-12

                                = -78+36-12

                                = -42-12

                                = -54

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 2
Anton [14]
Well , the diameter means a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. The area means what the extent or measurement of a surface or piece of land. So area means inside so all you need to do is  just to divide each side by knowing what 20/4 is and that = 5 meters

Find the value of x. Round the length to the nearest tenth.
STALIN [3.7K]

Answer:

x = 5.13 yards to the nearest tenth

Step-by-step explanation:

The diagram is redrawn and labelled in the attached photo.

It is labelled as triangle ABC. Angle A is determined to be 25 degrees. This is because it is alternate to 25 degrees at the top.

To find x, we will apply trigonometric ratio

Tan # =opposite side / adjacent side

Where # = 25 degrees

Opposite side = x

Adjacent side = 11

Tan 25 = x/11

x = 11tan25

x = 11× 0.4663

x = 5.1293 yards

x = 5.13 yards to the nearest tenth.
